Kubota Diesel Engine Wiring Diagram

To solve the leak into the atmospheric vent make sure your float level is adjusted perfectly. The float should be perfectly parallel to the upper carburetor body or sit slightly lower than level. This keeps fuel below where the two halves of the atmospheric vent meet. Also make sure your carburetor halves are not warped when the bolts are tightened down. If there is a visible gap between the two halves of the carburetor at the atmospheric vent; sand down the two halves until the gap is gone.
